Product details

The Pentair 470179 is the digital thermostat circuit board for MiniMax pool heaters, in the IID version. It is the genuine Pentair part.

What the board does

The digital thermostat board is where the heater reads its temperature set point and decides whether to call for heat. When it fails, the heater can look dead at the panel, refuse a new set point, or simply never fire even though gas and water are both fine.

Which heaters

Pentair lists this board under the MiniMax Plus and the MiniMax CH 150M to 400M heater parts. Confirm the model on your heater and confirm you need the IID board, because these heaters were built with more than one thermostat board.

Before you order

This listing is the board alone. Sensors, harnesses and the enclosure are separate parts, so if a sensor is the actual fault the board will not fix it. Diagnose the sensors and the wiring first, then replace the board.

Questions and answers

What people ask about this product, answered by our pool techs.

Which heaters use this board?
Pentair lists it under MiniMax Plus and MiniMax CH 150M to 400M heater parts.
What does IID mean on this listing?
It identifies the version of the board. Pentair built more than one digital thermostat board for these heaters, so order the IID board only if that is what your heater takes.
Does it come with the sensors or the wiring harness?
No. This is the circuit board on its own. Temperature sensors, harnesses and the enclosure are separate Pentair parts.
How do I know the board has failed?
Typical signs are a display that will not accept a temperature set point, a heater that ignores a call for heat, or a panel that shows nothing at all with power confirmed at the heater.
